T all whom it may concern:

Be it known that I, HARRY M'ELTZER, a citizen of the United States, and a resident of the borough of Bronx, county of Bronx,

city and State of New York, have invented certain new and useful Improvements in Elastic Resilient Cores for Automobile- Tires, &c., of which the following is a specification,

My invention relates more especially to automobile tires, although applicable to wheel tires generally. It is designed more partio' 1y for use as a substitute for the pneumatic nfi r tube used in wheel tires of this class, having all the advantages of elasticity and resilience, but being more substantial and effective because puncture proof i and essentially permanent in structure. Furthermore it can be more quickly applied to or removed from a hollow tread tire or casing, is cheaper, and may be folded into compact shape and area for storage or transportation.

The invention consists in the specific con-.

struction and arrangements of parts herein described and claimed, distinctive featuresbeing the articularly connected segmental subdivisions of the core, and the interposition ofc'oiled springs between the treadsupporting peripheral sections of the core and the rim or base sections of said core, all as hereinafter more fully set forth. 7

In the accompanying drawings, Figure 1, is a side-elevation of my improved elastic resilient tire core or filler,

partially in section;

Fig. 2, shows the same with the segmental subdivisions partially folded together;

Fig; is a transverse sectiontaken upon 40 plane of line 3-3, Fig. 1, but upon a larger scale;

Fig. 4, is a similar view showing the core inserted in a hollow tread shoe or casing;

Fig. 5, is a detail upon a larger scale of a p preferred form of articular joint used between adjacent segmental subdivisions.

My improved tire core is preferably made in five segmental subdivisions C, C C C and 0 although it may consist of any de .50 sired number of such segmental subdivisions as may be desired or found most expedient in adapting the core to tires designed for various kinds of traffic.

One of these segmental subdivisions,

C in the drawings, is preferably made somewhat shorter than the others to faciiitate manipulation when the core applied to or removed from a hollow cas1ng,such for instance as the hollow shoe type T, indicated iufFig. 4, in R, represents a clencher rim/of a wh- What may be designated as the 2r base-sections b, b, of the several segnu subdivisions ofthe core are articularly c nected together by any suitable or it known mechanical expedient that-"will mit of the subdivisions being inturned w relation to each other, as, indicated in 2, so that they, maybe folded into compact form vfor transportation or storage; but more particularly to facilitate their insertion into or removal from a hollow tire or casing, it being obviously easier to insert or remove the coresegmentally, one or more subdivisions at a time,'rat her than in its entirety as a complete annular structure.

The base sections 6, b, of the five sub divisions 0, C C C, and C, may be thus articularly and permanently connected together successively, the one to the other, as shown in Figs. 1, and 2,-by means of a pintle, or equivalent, 7?. The ends of the subdivisions may be formed with any form of hinge-joint. I prefer, however, the form of articular joint shown more particularly in Fig. 5, in which one part is chamiered OK as at o, to admit of the fold ing 0.1,: :the subdivisions into close relationship.

tread-supporting sections a, a, while the threaded inner ends 8, s, of said springs S,

S, engage with nuts 'n, n, which are countersunk 1n recesses b, 6, formed. for their re" ception in the base sections, 5, b, all as shown more particularly in Figs. 3, and 4, by reference to which it will be also seen. that the rounded wedge shape in cross section of the The base sections b, b, of the core outer sides of the base sections 5, 6, tends Y springs S, m. any suitabl' number of which may be included in each subdivision of the core, being made of suitable elastic resilient material, as tempered steel or the equivalent, are an effectual substitute for the air cushion heretofore used in the form of the Well known pneumatic tube; and the peripheral tread supporting sections a, a, being rigid, reinforce and sustain the peripheral or tread portion of the hollow tire or casing T, more effectually than the rubber pneumatic tube.

Ly improved tire core is simple, cheap and effective, is puncture proof, and has many other practical advantages over the pneumatic core which it is designed to replace. l urthermore its durability and life far exceeds that of many pneumatic cores or fillers, and it is easily appliedjto or removed from a hollow tire without special preparation or the use of special implements. It is always filled and ready for application and use; and extra cores may be stowed away in small space, out of sight in the vehicle in case of emergency, although as a matter of fact the danger of injury to my core under ordinary conditions of use is so remote as to render such duplication only Q menses apreeautionary measure, and not an absolute necessity as in the case of the pneumatic core.

lVhat I claim as my invention and desire to secure by Letters Patent is,

1. A separable insertible core for tire casings such as designated, comprising a plurality of articularly connected segmental subdivisions, each consisting of a base section and a peripheral tread-supporting section united by coiled springsinterposed between them'and connected therewith.

2. A. separable insertible core for tire casings, comprising a plurality of segmental subdivisions, each subdivision comprising a base section and a peripheral tread-supporting section curved to conform to the curvature of the casing, springs interposed between and uniting the base sections and the tread-supporting sections, and means articularly connecting together the adjacent ends ofthe base sections.
